Transcript for Running Wild: Close Encounters With Packs of Coyotes on the Rise

And as we've been reporting, an on going drought in the west. Tonight, a new question. Is it causing some close encounters in suburbia with wildlife? Coyotes descending, all caught on camera. Nick watt reports. Reporter: One man and his dog, running scared in suburban Burbank, California. Here's why. Coyotes on the hunt. I saw four to five coming at he. Then I paused. I saw about ten coming out. They were just coming out like a horror movie. Reporter: Coyote sightings are not uncommon in southern California. But close encounters like this are on the rise. One theory -- the severe drought is sending wild animals into human habitats in search of food and water. They are exhibiting strange behavior. Very strange behavior. Predatory. Reporter: Wildlife and urban sprawl always make awkward bedfellows. We've seen a mountain lion in a Santa Monica office building, a bobcat that broke into a prison in Washington state. But now, here in malibu, the city is advising residents "Animals are being seen more often in the middle of the day, are more aggressive and can be destructive." The advice, don't leave kids or cats outside unattended. If you'd heard, that's the screeching noise. I mean, it's like, awoo! Some animal being completely taken apart. Reporter: Even when he waved a shovel, they wouldn't leave. Nick watt, ABC news, los Angeles.
